1. A method of video decoding performed at a computing system having memory and one or more processors, the method comprising:
receiving video data comprising a picture, wherein the picture is coded using at least a first color component and a second color component, and wherein the picture includes a first block that is coded in a geometric partition mode, the first block comprising a first geometric partition and a second geometric partition;
reconstructing samples in a first geometric partition of the first color component of the first block using the first geometric partition;
deriving the second geometric partition for the second color component of the first block based on the reconstructed samples of the first color component of the first block;
reconstructing samples of the second color component of the first block using the second geometric partition, wherein the first geometric partition is different than the second geometric partition; and
decoding the first block in the picture based at least on the reconstructed samples in the first geometric partition of the first color component and the second color component of the first block.
